Application filed May 2l, 1900. Serial No. 17,384. (No model.)

To @ZZ whom lwftyconcerm Be it known that I, FRED W. FELBAUM, clergyman,a citizen of the United States, re-

siding at Dayton, in the county of Tippecanoe and State of Indiana, haveinvented new and useful Improvements in Mixing and Vaporizing Devicesfor Explosive-Engines, of which the following is a specification.

This invention relates to that class of engines operating by virtue ofthe force of successive explosions of the vapor generated from suitablevaporizing oils, and has particular relation to the means for vaporizingthe oil.

The invention has for its objects the automatic controlling of the IloWof oil into the vaporizing-chamber, so that it will be fed according tothe requirements of the speed at which the engine may be operated, asWell as to automatically cut o the oil flow to prevent the flooding ofthe Vaporizing-chamber should the engine for any cause come to a stopunobserved, the distribution of the oil flow Within thevaporizing-chamber whereby to more readily expose the oil to currents ofair for its'quick and thorough vaporization, and finally the making ofsuch provision whereby a supply of oil may be contained in thevaporizing-chamber for the immediate source of the feed and not bedisplaced or otherwise affected by the force of the vaporizingair-currents.

The invention consists in certain novel features in the arrangement andconstruction of parts, all as hereinafter described and claimed.

The accompanying drawing, forming a part of this speciiication,represents a vertical section taken through the vaporizing-chamber, theoil-feeding receptacle, and the distributing-cone.

The vaporizing or oil-mixing chamber l is located,preferably, below thechamber 2, a portion of which only is shown, and by which the oil-vaporis conducted from the vaporizingchamber to the combustion-cylinder ofthe engine after the usual Well-known manner. The opening 3, by whichchambers l and 2 communicate, is closed by a valve-disk Il, which isoperated automatically by suitable connection Withthe engine, whichimparts reciproeating motion to the valve-stem 5, on which saidvalve-disk is mounted. of operating the valve-disk 4 from thevaporizng-chamber said chamber is formed at its top With a lateralright-angle portion la, and through which extends the valve-stem 5. Themajor portion of the vaporizing-chamber is preferably in cylindricalform and has its bottom provided With air-inlets 6. Supported on thebottom of this chamber is a hollow conical frustum 7 of a diameter atits lower end preferably equal to the inner diameter of the bottom ofsaid chamber, the said frustum being provided with a circular base 7band forming an interior chamber '7a to receive the incoming air andbring it in contact With the oil Which is fed onto the inner face of thechamber. Supported on the top of this conical frustum is an annularreceptacle 8, which is preferably formed integral With the frustum. Thisreceptacle is connected byapipe 9 with a suit-able oil-supply soelevated above the receptacle as to cause the oil to liow from saidreceptacle through the outlet l0 by force of gravity. The oil-outlet iseither in the form of a circular slot or of separate openings madeaslaut in the inner upper edge of the receptacle, the said edge beingbeveled` to form a seat 1l for a valve-disk 12, which being in the formof a puppet-valve closes the outlets 10 when resting in its seat Withoutentirely closing the central opening through the annular receptacle.

Extending through the center of the bottom of the vaporizing-chamber andthroughout the length of said chamber and fitting Within a screw-plug13, inserted through the top thereof, is a rod 14, mounted to have aslight reciprocating movement, and upon which are secured the valve-diskl2 for controlling the oil-feed openings l0 aud the For the purpose Yvalve-disk l5, which has its seat on the bottom of thevaporizing-chamber over the openings 6,but Which only partially closessaid openings. This valvedisk 15 is loose on the rod let and has slightvertical play, that being limited by the collar 16, adjustably securedto the valve-rod.

The Walls of the oil-mixing chamber 7 are IOC) ' globe-valve 18 islocated in oil-supply pipe 9,

by which the pressure of the oil may be regulated.

The operation is as follows: 0n the suctionstroke of the engine thevalve-disk 4 is mechanically raised, opening the communicating passagebetween chambers 1 and 2, controlled by said valve-disk. As the valve-.

disk 4 travels with the outward stroke of the valve-stem 5, a slightvacuum is produced in the chamber l, and the atmosphere tending toequalize conditions forces thro ugh the partially-closed openings 6 andraises the valvedisk 15 and in so doing raisesthe valve-rod 14 and itsvalve-disk 12. The force of the air-pressure will be suicient onlyto'effect a quick rising movement of the valve-disks, when from gravitythey will immediately seat themselves. During the rising and closing ofthe valve-disk 12,which will occur synchronously with the operation ofthe engines piston-stroke or the stroke of the valve-stem 5, operatingvalve-disk 4, the oil will be fed from the oil-receptacle 8, whichcontains a supply of oil to respond in vits flow to the varyingrequirements of the engines feed, as the periodicity with which thevalve-disk 12 will operate will be automatically governed thereby. Theoil-reeeptacle having its outlet abovethe highest point of theoil-containing space, the jar or commotion of the air within thevaporizing-chamber is prevented from displacing the oil or having anydisturbing effect upon its natural flow. The oil iiowing down on theinner side of the oil-receptacle through the central openingtherethrough continues down in a streamon the inner wall to the conicalchamber Wand vby the increasing surface is distributed so as to form avery thin film. The air rushing in at openings 6 is thus not onlybrought into contact with a large surface onto which the 4oil has beenspread, but is choked by the converging s`ides of the chamber, as in themanner heretofore stated, and caused to escape through the perforations17 with sufficient force to break up the particles of oil and make thevaporization not only the more rapid, but very thorough.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- 1.
